Unsteady Boundary-Layer Flow over Jerked Plate Moving in a Free Stream of Viscoelastic Fluid

الملخص EN

This study aims to investigate the unsteady boundary-layer flow of a viscoelastic non-Newtonian fluid over a flat surface.

The plate is suddenly jerked to move with uniform velocity in a uniform stream of non-Newtonian fluid.

Purely analytic solution to governing nonlinear equation is obtained.

The solution is highly accurate and valid for all values of the dimensionless time 0 ≤ τ < ∞ .

Flow properties of the viscoelastic fluid are discussed through graphs.
